To all 'whom 'it may concern:

- Beit known thatgI, J AMES P. MCCR'EADY, a

citizen of the United States, and a resident of Berlin, in the county of' Coos and State of New Hampshire, have invented a new and Improved Pulp-Lap-Forming Machine, of which the following is a full', clear, and exact description. i

Among the principal objects which the present invention has in view are: to provide a mechanism Vforforming la s of designed' thicknesses .and i density,

storage or'trans'porta'tion; to provide a mechanism continuous in its operation for build'- ing up a lap of desired thickness, severing,

land folding the same in shapes of constant dimensions; `to provide in a mechanism of thecharacter specified means for regulating 'the quantity of .pulp futilized to form the laps; and to provide in la mechanism of the character specified automatic controlling dethe present invention ;,V Fig. 2 is a rear view of the same, the felt conveyer belt for delivering tothe said machine being shown in section; Fig. l3 is a plan view of the same; Fig. 4 is a vertical cross section of the machine takenon the-line 4 4 in Fig. 3; Fig. 5 is a vertical longitudinal section of the ma chine takenon the linee-5 in Fig. 8; Fig.- 6 is a detail View. oi. thefolder arm and operating mechanism, connected therewith; Fig: 7. is a viewin cross section of the rollers for operating the conveyer for accumulating the pulp; thepulp being shown in the operation of upbuildingglFig. 8 is a View similar to that shown in Fig. 7 illustrating the Separation of the formed lap from the accu-A mulator roller;Fig. 9 is a detail view in vertical` section, illustrating in part the instrumentalitiesfor lstripping the accumulator rollerof the formed lap, and forfolding and delivering the same; Fig. 10 is a detail view in vertical cross section of the conveyer belt and folding table; Fig. `11 is a `detail Y olded ing vcompact form for further manipulation,

v4is employed the suliite 24, 24 of the frame ofl the machine.

View in fragmentary form, illustrating the guide switch 4for controlling the action of the stripping clamps for removing the laps from the accumulatorroller; and Fiv 12y is a detail view in side elevation showing the movable. jaw of the said clamp.

The machine herein illustrated is desi nedto formV the pul after lthe same has )een digested and was ed intoshapes forstorage,

further handlin or transportation. These sha les are padike in form, being folded wit in as small `on area asV convenient, thereby increasing the thickness of the shapes. The` folded article may, if desired, be pressed to eliminate any 'remaining moisture, and then stored or transported." .This shape is termed in the art a lap. In the resent machine these la s are automatica lyremovedfrom the leed belt and accumulated in sheet form of required thickness. to produce the required weight.

by weight. From the accumulator roller the sheet of laminated pul is removed, outsprcad on a suitable tab e, and there folded to the required dimensions. From the told- .ing table the lap is delivered from the present machine to a suitable receptacle or conveyer,.by which it is removedto be packed for storage, for transportation, or rehandled as by pressure, to remove any .of the remain 'ing sulite or soda solution, if-thepulp has been treated-by the soda process. In the present employment the machine is used by me in conjunction with pulp mills in which process for digesting the cellulose.

Fromithe digester, or mechanism immediately connected therewith, is extended the usual felt belt conveyer 21. The conveyer 21 is extended around and driven by a roller 22. The roller 22 is `iixedlynlounted on a shaft 23, supported in bearings in the sidAes n accumulator roller 25 is provided with trunnions 26, 26. The roller 25 is rotated by the roller 22 because of the frictional contact with thesurface of the conveyer' 21 thereon. The roller 25 vis held in frictional engagement with ythe roller 22 4and conveyer 21 by springs 27, 27, which are mounted in hollow pedestals 28, 28 to bear upon rods 29, `29, at the lower ends whereof are provided suitable bearings 30, 3() which rest over Aand form bearings for the said trunnions `26, 2,6.

75 The laps, when dealt in by the pulp manufacturer, areV sold Mounted in the )cdestals 28, 28 and in the hollow thereof, a ove the springs 27, 27, are

set screws 31, 31. By means of the set screws 31, 31 .the initial pressure of the roller upon the -roller 22 and conve er 2l is` between the rollers.

By the mountin and arran ement above described with re erence to t e rollers 22 and 25 it will be seen that the movement of the rollers is harmonized, in that the rollers Vrotate simultaneously and at the same peripheral speed, and that the conveyer 21 is moved in perfect s nchronism therewith. The action of the rol ers and conveyer is intermittent. Y During'theinterruption of the rotation the accumulated pulp, which has been gathered upon the accumulator roller 25, is severed longitudinally on the accumulator roller by knives `32, 32, which, during the cutting opera-tion, travel from the extreme periphery of the roller, as seen in F ig. 4 of the drawings in full lines, to the median line of the said roller, as seen in dotted lilies in said Fig. 4.

According as the weight for the completed lap is varied, so is the thickness of the pulp .cylinder varied. yThe thickness of the pulp cylinder depends upon the number of windings or convolulions ofthe pulp delivered by the conveyor 21 to the roller 25. This having been determine-d, the rollers 22 and 25 are arrested when the designed number of convolutions has been placed upon the roller 25. In the moment of arrestation of the saidl rollers the knives 32, 32 are advanced sin'niltaneously and longitudinally across the roller 25 until the cutting edges meet on the median line, as shown in dotted lines in Fig. 4 of the drawings. Each of the knives 32 is mounted in a perforation formed in arms 33, 33, wherein they are adjusted by set screws 34. The arms 33, 33 are xedly mounted upon racks 35, 35. The racks 35, 35 are provided with gear teeth 36, 3G, meshed with the teeth vof an interposed pinion 37. The pinion 37 is fixedly mounted on a shaft 38, by which the said inion is rotated to move the said racks 35, a in a frame 39 wherein they are guided by a groove formed in the upper and lower edges formed inthe said frame by inwardly extended flanges 40,40.

The shaft 38 upon which the pinion 37 is mounted, is supported in bearings in a face late 41 and a cross head 42, as shown in Fig. v5 of the drawings. At the end of the said shaft removed from the pinion 37 there is fxedlyjmounted a bevel gear wheel 43. The bevel ear wheel 43 is in meshed enga rement wit a com anion bevel gear whce 44, ixedly mounted upon a shaft 45. The shaft 45 is mounted in bearings formed in the sides 24, 24 and in a standln frame 46 beyond on the said sides 24 an alincd therewith on the salne bed plate. The saidshaft is provided, between the standard 46 and the adjacent side 24 witha gear wheel 47, and a grooved pulley 48, both being fixedly mounted on the said shaft 45. Pivotally mounted on the shaft 45 is a'swinging nido frame 49, the sides whereof stra( dle t 1e gear wheel 47 and support rotativcly at the end of the frame 49 guide'wheels 50, 50. The wheels 50, 50 are provided with two extensions of diiierent diameter, the smaller diameter serving to receive the thrust of a rack bar 51, and to maintain Vthe same in meshed disposition on the gear wheel 47. The larger diameter or extension of the wheels 50, 50 depends at the side of the said ruck and maintains the same in position against one side of the frame 49.

A rack 51 is employed to rock the shaft 45, and is maintaine in constant engagement with the wheel 47, and therethrough with the shaft 45, the bevel gears 44 and 43, shaft 38, pinion 37 and racks 35, 35. Through this transmission mechanism the knives 32, 32 are moved to and from the median line of the roller 25 as and when the said rack 5l is reciprocated. The reciprocation of the rack 51 is produced by a lever 52, which is pivotally enga ed at 53 with the said rack. The lever 52 1s fixedly mounted on a shaft 54, which is su )ported iu bearings in standards 55, 55. llxedly mounted on the shaft 54 is a ear wheel- 56, which is held in meshed re ation with a large gear wheel 57. The ear wheel 57 is loosely mounted on the sha t 23, and is fixedly secured thereto by means of a clutch 59, which is slidably mounted on a feather 60. lThe clutch 59 is provided with a truncated face 61, to engage the truncated face 62 of the wheel 57. The clutch 59 is held in longitudinal disposition on the shaft 23 by a ring 63, which is mounted in a groove in the said clutch, and which is held therein by pins 64 set out from the side of the said ring and held within the yoke 65 of an arm (36. It is only when the arm G6 moves the clutch 59 to engage the rear 57 that the transmission mechanism fdr operating the knives 32 is set in motion. The arm 66 is normally maintained in disengaged position by a coiled spring 67 which infolds a shaft G8 and is disposed between the frame 24 and the hub of an arm 69, which is fixedly mounted on the said shaft 68. The arm 69 is extended, and at the upper end provided with a roller 70 which bears against the side of a gear wheel 71, which is fixedly mounted upon the shaft 23. Extended from the opposite side of the said wheel 71, and in diametrically o posed arrangementthereon are cam risers 2 and 73. The risers are provided with inclined surfaces 74, 74, by which the rollers 70, mounted on the ends of the arms 69 and 75, travel. The arm 69,V when moved by the riser 72, shifts the shaft 68- inward against the expansion of the spring 67, and through the arm' 66 closes the clutch `59 upon 'the truncated face 62 of the wheel 57. Tn this position the transmission mechanisln ,just above described is operated to rotate the pinion 37 to` move the racks 35, 35 in such manner as to bring the knives 32, 32 to the median line of the roller 25, cutting through the accumulated pulp covering of the said roller 25, and severing the said cover to convert the cylindrical shape thereof to a flat like member. This operation is, in comparison with the travel of the periphery of the roller 25, rela'- tively rapid, andthe line of cut is substantially straight. 1n the operation of the machine as hereinafter set fort-h, the knives 32, v32 are arrested in the position at the center of the said roller 25. The rack 51' of the transmission mechanism just described is raised to project upward and outward throughvthe guide frame 49. The cam 7 2 is formed toa length to pass from under the roller 70 at this. instant, kpermitting the spring to shift the shaft 68 in such manner as to throw the clutch 59 eout of engagement with the gear wheel 57. The transmission mechanism and knives 32 are returned from this positionby the rotation of a wheel 86,

' which isl fixedly mounted on the shaft 54 described.

to which the lever 52 is likewise attached.

The operation of thewheel 86 for the re-tf turn of the knives 32 Lwill be hereinafter The stripping mechanism. employed for removing the pulp from the roller 25 consists primarily in jaw members 89`and 90. There are duplicate sets of these jaws, mounted on opposlte sides of the machine in guide l frames, whereofthe rods .91, 91 are4 extended through perforations. in a carriage 92. The. stationary jaw 89 is fxedly secured tothe carriage 92 by screws 93, 93, or other suit-V The jaw 90 isupivoted to the movement to and from the `jaw 89 .by pins- 95 extended from the side of an arm 96` of the said jaw 90, 'and providedwith a small roller 97. The pin 95 and roller 97 thereon` extend into the upper andlower track slots 98 and 99 respectively. The slots 98and 99A are separated by a late 100, and are connected at the ends y connecting slots 101 and 102. The connecting slot 101 is atfthe forward end ofV a plate 103, in which `the above mentioned slots. areformed, and is at all times free for the pin 95'to drop there'- through from the upper slot 98 to the lower Aand outwardly inclined, being disposed in slot4 99. The connecting slot 1,02 is closed at y the upper opening thereof by the overhanging end of a spring 104, as shown in Fig. 1l

of the drawings. `The slot 102 is upwardly .such manner that when the ]aw 90 is re` tracted the pin 95, and roller mounted thereon, are' caused to lift upward from the slot 99 through the said slot 102 to the upper slot 98. In passing from the slot 102 to the 75 slot 98the pin 95 displaces the end of the spring 104. .At the outer end of the slot 98 .is an extension 105, into which the pin 95 is drawnat the extreme outward movement of the carriage 92, Acarrying the aws 89 and 90. This movement of the pin 95 into the exten` sion 105 permits the spring 104 to close the slot 102. On the return in a forward direction of the carriage 92, the pin 95 overrides the slot 102, and is maintained on the upper level of the slot 98. lt is between the -iaws 8.9 and that the lower severed edge of the pulpon the roller 25 is engaged. This engagement occurs when the carriage 92 has been drawn forward' to a-position where the forward "edge of the jaw 89 is under the outwardly hanging edge of the pulp which has been severed, and when the` upper jaw 90 is extended over the said severed edge of the pulp.l As extended at the forward end of the plate 103, the connecting slot 101 isopen, so that the -pin drops into the said slot, and when the carriage 92 is retracted, the pin 95 is forced under the plate 100, andthe outer end of the jaw 90 is forced into engaging relation with the pulp interposedbetween the saidjaw and the jaw 89. 'To Aadvance the carriage 92, grooved pulleys 106, 106 are fixedly mounted upon the shaft 45. The shaft 45, it will 4be remembered, is the controlling shaft for the operation of the` knives 32, 32. The rotation of the shaft 45 to advance the knives 32, 32 to the median line of the roller 25, rotates the VpulleyslO, 106. in the direction shown by V1-10- the arrow in Fig. 5 of the drawings. This rotation of the pulleys 106 winds the cables -107 thereon. The cables 107 are connected y at 108 lto the carriage 92. As above stated, `,the mechanism for moving the knives V32,

V 32 moves rapidly in comparison. with the Vperiplfieral travel of the roller 25. The ad- Vweights '112, 112, which are mounted on thel ends of cables 113, 113 passed over sheaves 114, 114and connected to the car-l riages 92, 92 'at 115, 115. The weights 112 -are ofany desired dimensions necessary to accomplish the retraction ofthe said carriages. The carriages' are controlled in their 130 i'etrogressive moiiement by the wheel 86, which is mounted on the shaft 54 carrying the lever 52 and the rack 51. The wheel 86 is operatively connected to a pulley 109 by a crossed belt 110. The pulley 109 is ixedly mounted upon a shaft 111. The shaft 111 supports a conveyer roller 116, whereon is gui ably su ported a belt 117, which constitutes the elivery member of the table on which the sheet of pulp is spread by the stripping mechanism, and the jaws 89 and 90 thereof. As the sheet of pulp is delivered from the rollers 22 and 25 it rests upon the belt 117, and compels the same to travel therewith. Through the shaft 111, the pullqys 109 and 86 and the belt 110, the pull o the wei ht 112 is diffused and removed from the iminished areas gripped by the jaws 89 and 90, the bod of the pulp sheet forming a drag on'the belt 117 and transmission mechanism interposed between the shafts 111 and 45.

By reason of the disposition of the slot 102, when the jaws 89 and 90 have passed to the outer position necessary to place the sheet' upon the belt 117 and parts connected therewith, to form a folding table, the jaw 90 is lifted, and the ri vof the stripping mechanism is released fiiom the sheet of pulp. From this point the further retraction of the carriages 92 is uncontrolled and actuated by the maximum pull of the weights 112, retracting the carriages 92 to their full outward limit, and placing the ins 95 at the end of the extension 105.

ith the return of the carriages 92 to the limit of their outward position the shaft 45 has been returned to its normal position wherein the racks 35, 35 havebeenlaterally extended to carry the knives 32, 32 to the edge of the roller 25.

In the operation of this invention, as above stated, the ulp is received .from the belt 21, and a numer of layers are rolled upon the roller 25 under the pressure of the springs 27, prior to the action of the knives 32, and the stripping mechanism as above described. At the moment when the knives sever the cylinder of pulp,.the said cylinder is provided with a layer on the forward section of the roller 25 notyet de osited on the rearward portion of the said cylinder.' As the severed edge of the said c linder is drawn outward to be placed on t e folding table, the rotation of the roller 25 lays a single thickness of the pulp u on the section of t-he severed cylinder or s eet until y the rearwardly disposed edge of the sheet passes from between the rollers. When the full weight of thepcarriages 92, 92 and the pulling weights 112, 112 are thus transferred to the single layer of ulp which follows the sheet `drawn from t e cylinder, the ul is separated or torn as the compile sheet passes from the grip of the rollers 22 and 25.

F rom this iiionient, that portion of the ulp which consists of manifold layers, and w lic i is above referred to as a cylinder, is plated on a folding table as a separate outspiead sheet of the desired thickness, while the free torn end of the single thickness bein de'- livered by the belt 21 is passed aroun the roller 25 to be overlaid by the required number of convolutions of added pul to form the succeeding cylinder or sheet. Irl`he operation of the roller is continuous havin r formed thereon successively the cy inder o pulp which is severed an stripped therefrom when and as the cylinders have received the desi ed number of pul thicknesses. The su sequent folding of t e sheet does not interrupt the formation of the succeeding cylinder. In this manner the operation of the present machine is automatic and continuous.

The folding mechanism whereby is formed the lap is operated by a mechanism embod ing the wheel 80. The wheel 80 is loose y mounted on the shaft 23, with which it is fixedly engaged by means of the sliding clutch 81, the truncated face 78 whereof is ada ted to engage the truncated face of the hu 79 formed on the wheel 80. The clutch 81 is connected to the arm 85 by means of a collar 82, pins 83 and a oke 84, as seen in Fig. 2 of the drawin s. T e arm 85 is xedly mounted on the s aft 76, having suitable bearings in the sides 24 and the standard 55. The shaft 76 is infolded by a sprin 77 restin r between one of the bearings or the sai shaft and the hub of the arm 85, and dis posed in such manner as to normally remove the clutch 81 from engagement with the hub 79 of the wheel 80. Fixedly mounted upon the said shaft 76 is a second arm 75, the upper end whereof is provided with a roller adapted to rest a ainst and track upon the side of the wheelg71, and in the-path of the cam 73 mounted thereon. The cam 73 is disposed with reference to the cam 72 in timed relation. It will be remembered that the cam 72 operates upon the arm 69 to engage the wheel 57 to operate the knives 82 and lift the carriages 92. The subsequent operation of the knives and carriages has been described. It is at the moment when the said carriages 92 reach the end of their outward movement that the cam 73 passes under the roller 70, shifting the clutch 81 to rengage the wheel 80, and thereby inaugurate the operation of folding.

The shaft 88 isextended beneath the folding table and mounted in suitable brackets formed in the sides 24, 24, and standards 55. FiXedly mounted on the said shaft, and in meshed engagement with the wheel 80, is a gear wheel 87 whereby, when the wheel 80 is rotatively engagedwith the shaft 23, the shaft 88 is rotated by the wheel 87. The gears and 87 are equal in diameter, thereby cansino' `the shaft 88 to rotate iny unison lebe with the s aft 23,imparting thereby .a complete vaction of the folding mechanism as cont-rolled by. the cams' carried on the said shaft 88 during .the one revolution of the rollers 22 and 25.

The folding members of the folding mechanism consist primarily in forward folding lingers 118, 118 and laterally folding plates 119, 119. The' operation of these members is successive, the initial'operation being the lift of the fingers 118 to upwardly bend across the full width and at the median line thereof, the sheet after the same has en stripped from the roller 25. This Vbend folds the said sheet in two layers, the double sheet then resting above -the belt 117 and the plates 119, 119.` rlhe plates 119, 119 are hingedly connected to a stationary structure substantially equal in length to the said, plates 119. The folds formed by the said .plates 119 are onethird of the length` ofthe folded sheet, or the Width of theoriginal sheet.V The plates 119 operate successively, Vfolding from Afirst the one side and then'the other. It will be observed that the final folded lap 4is entirely supported upon the belt 117. 'When in the operation ofthe stripping mechanism succeeding the completion of the folding of the lap, the belt 117 is moved, the lap is, by the said belt, carried outward from the machineto be delivered over the outward extension of the said belt 117. The fingers 118 are tixedly mounted on a lshaft 120, which is mounted in suitable bearings in the side 24 of the frame. At'the outer end the shaft 120 has fixedly mounted thereon a small gear wheel 121, the teeth whereof are meshedwith the teeth of a largegear Wheel 122. The wheel 122 is mounted ona rocking shaft 123, and is provided with roller equipped pins l124 and 125 set out from the surface of the said wheel. vIt jis by the manipulation of the Wheel 122 by the'V cams 126 and 127 operating uponV the 'said pinsk 124 'and 125 successively, -andin the order named, that the shaft 120 isvregulated to lift the fingers 118, 118 from-.the reculnbent position shown in Fig. 3,by and overthe plates `119, 119, and bend and :fold the sheet of manifolded pulp previously spread above the said lingers.l The-cams 126and 127 are shaped as shown in Figs.v l, 2 and'4 of the drawings. The cam 126'is .ofthe usual shape, the voluted face thereof playing upon the pinV 124 to raise thesameV from the position shown in Fig. 1 Vof the drawings to a position sufliciently removed from the shaft 88 to' errnitV the cam 126 to pass under the said p1n4124.' The movement 4 of the pin 124 above described results in the rotation of the wheels 122 and -121'sutficient .to raise the fingers 118, 118 overupon the plates 119, 119. `The movementof the wheel122 sufficient to accomplish this places the pinr125 in the path ing'the shaft 120` to return the finger-S118,

118 to their initial position. The cam 127 isbent, as shown in Figs. 2 and 4 of the drawings, in such manner that the said cam overrides the pin 124 inthe position which the saidpin 124 assumes when the pin 125 has been moved out of the path of the said end 128 ofthe cam 127.

Cams 129 and 130 are lixedly mounted upon the shaft 88, and alternately move the roller equipped `pin 131 from and to the median line of the machine, or the normal position illustrated in Fig. `4 ofthe drawings. (Ja'msM132 and 133'operate successively to shift the roller equipped pin'134 to and from the median line ofthe machine, or the position illustrated in Fig. 4 of the drawings. The two sets of cams are oppositely disposed, that is to say, Vat themomentwhen the cam 129 is moving the pin 131 outward,

the cam 133 on the opposite side of the me-` dian line ofthe machine is moving the pin' 134 inward. The pins, 131 and 134, are con-l nected to slide plates, as shown in Fig. 4 ofv 24 ofthe machine, and provided with guide rollers 138,V 138, mounted .on shafts 139, 139, separating the sides of the channeland disposed above the plates`135 and 136 to guide the reciprocation of the said plates in the said channel. The plates.135 and 136 are each provided in the upper surface with grooves 140, 140. Links 143 and 144 are pivoted at 141 and 142 in the Vsaid grooves, said links being respectively Aconnected to the plates 135 and 136. Thelinks '143v and 144 are pivotally connected to lugs 145.and i 146, integrally formed with the plates 119,

119. The plates 119lare each pivoted at 147, v1 47 to hinged links 148, 148.v The hinged `links 148, 148 are ivoted at 149 to the frame of the channe4 137. The links Aand lugs above mentionedA are proportioned to produce in the plates 119 to" which they are connected, a com" lete' overfold` of each of the plates above t ebelt 117. Byy reason of thealternate and successive `action of, the cams 129 and 130,"an`d thecams 132 and -133, the lates 4135 and 136ar`e alternately shifted to old the said lates 119 alternately. As above stated, in tlhusfoldingv theplates119,

the lap is completed, the result being a packet :of pnl of a definite weight and di-4 mension, the dimension being in area equal to one-half the length of the original sheet A the said shafts controls the number of layers hub of the pinion 155.

of pulp placed on the roller 25 between the operations of the 'strip ing mechanism. The operation of the stripping mechanism is directly resultant upon the rotation of the shaft 153 through the operation of the cam wheel 71, which is in mesh with the inion 155 loosely mounted on the shaft 153 1n line with the said wheel 71. A gear wheel 156 is fixedly mounted upon the shaft 23, and is in mesh with a gear wheel 157 fiiiedly mounted upon the shaft 153. The drlving of the shafts 23 and 153 is obvious, being through the pulleys 151, gears 152, 154, 156

and 157, the said shafts rotating in definite timed relation due to the operation, of the meshed geais 152 and 154, and each shaft continuously driven. The pulleys 151, as shown in the drawings, are the usual arrangement of iixedand loose ulleys.

Any suitable form of shiftlng device for ,the driving belt may be used in conjunction with this machine.

The o eration of the strip ing and folding mec anisms, inaugurate by the cam wheel 71, may be independently controlled by the clutch 158, which is slidably mounted lon the shaft 153 and the truncated face of which meshes with the truncated face of t-he The clutch 158 is controlled by a lever 159, the end whereof is extended as shown in Fig. 1 of the drawings, which lever is pivotally mounted at 160 in brackets 161 set out from the side of the frame. The lever 159 is provided with a yoke 162 engaging the cont-rolling collar of the clutch 158. By manipulating the lever 159 the stripping and folding o eration may be controlled independently o the feeding and cylinder forming mechanism. In other words, if at any time it is desired to increase the thickness of the wall of the cylinder of pulp formed on the roller 25, this may be aeoomplished by manipulating the lever 159, discontinuing the operation'of the stripping and folding mechanisms, allowing an added accumulation of pulp to the cylinder being formed on the roller 25. A further use for the control operated by the lever 159 is to set the time of operation of the knives 32, 32 with reference to the pulp accumulating mechanism.

The conveyer belt 117 is constructed in the shape of an endless belt, and is guided and supported on idler rollers 116 and 163, 163, sal rollers being disposed to the best advantage with reference to the other mentioned mechanisms.
